YARN CREEL Filed 00'0- 8, 1962 INVENTOR CIMRLES H-MEGILI.

ATTOR E) United States Patent 3,126,695 Y CREEL Charles H. McGill, Decatur, Ala., assignor to Monsanto Chemical Company, St. Louis, Mo., a corporation of Delaware Filed Oct. 8, 1962, Ser. No. 229,239 1 Claim. (CI. 57-18) This invention relates to creels and more particularly to creels from which yarn ends can be fed in a composite bundle.

In the manufacture of chemical filaments or tow it is sometimes necessary to pull several yarns or tows off bobbins or warps and combine them for a crimping or other operation. In a conventional system the yarns are merely brought together to form a bundle and then advanced along a path. This bundle is usually difficult to hold together. The yarns or tows formed from filaments in the bundle tend to separate, making the recrirnping or other operation more difiicult and not quite as successful. With this in mind, one of the objects of this invention is to provide a novel and improved creel.

Another object of this invention is to provide a creel wherein several yarns or tow ends are combined, with one of the ends being wrapped around the others.

A further object of this invention is to provide a creel wherein several yarn or tow ends pass in a bundle axially through a ball warp from which another end is applied to the bundle.

One embodiment of the present invention contemplates a creel wherein yarn or tow ends from a plurality of ball warps are assembled into a bundle and passed axially through the core orspool of a central ball warp. The yarn or tow on the latter warp is drawn off with the moving bundle. Because the bundle passes through the central warp the yarn from the central warp is wound around the bundle to hold it together.

Other objects and advantages of the invention will become apparent when the following detailed description is read in conjunction With the appended drawing, in which the single figure is a perspective view of one embodiment of the invention showing the general construction of the apparatus.

Referring now in detail to the drawing a base 11 is shown supporting a plurality of stands 12 which in turn support a plurality of ball warps 13. A raised central stand or frame 16 supports a central ball warp 17. The frame 16 is provided with vertical legs 20 which support a plate 21 upon which the central warp 17 is positioned. A tube 22 secured to the lower surface of the plate 21 directs yarns or tows 25 from the warps 13 through an 3,126,695 Patented Mar. 31, 1964 aperture (not shown) in the plate 21 and axially through the central opening in the core or spool of the central warp 17. These yarns or tows are thus combined at the lower end of the tube 22 and travel through the central warp 17 as a bundle of yarns or tows.

A frame 30 supported above the base 11 by posts 31 is provided with eyelet guides 32 each of which is positioned directly above one of the warps 13 so that the yarn or tow 25 balloons off the warps 13. The yarns or tows 25 follow paths which lead from the warps 13 through the eyelet guides 32, over rods 34 which are a part of the frame 30, and under rods 37 secured to the legs 29, and into the tube 22. In this manner the yarns or tows 25 are tensioned by passage over the rods 34 and under the rods 37 and are combined into a bundle 38 and passed through the central warp 1'7. Yarn or tow 39 from the central warp 17 is drawn off with the moving bundle 38. Since the yarn 39 is wound around the warp 17, this yarn will balloon off and wrap around the moving bundle of yarns as shown. This wrap holds the bundle of yarns or tows together for subsequent processing. This holding together of the yarns or tows assists materially in the success of the subsequent recrimping or other process.

It is to be understood that the embodiment disclosed herein is merely illustrative and that numerous other embodiments can be contemplated without departing from the spirit and scope of the invention.

What is claimed is:

A creel, comprising a base for supporting a plurality of spaced first yarn warps, a frame mounted on the base, a plurality of eyelet guides secured to the frame at positions above said warps for controlling the ballooning of yarns drawn from said first warps, said frame having therein a plurality of first guide rods, a raised stand mounted on the base for supporting a central warp at an elevation above said first warps, said central warp having therein a central opening, a tube secured to the stand for di recting yarns from said first warps through said central opening, and a plurality of second guide rods mounted on the stand below the tube, said second rods being lower than the first rods so that yarns from the warps pass over the first rods and downward and under the second rods before passing to the tube.
